[Echographic symptomatology of peritonitis encapsulans].

The authors, try to establish an approach about ultrasonic pattern of capsulated peritonitis through study of four cases. The echographical semeology of this affection is based on: echoscopic signs which study the intestinal mobility and lumen, and the associated ascits: --echographic signs represented essentially by: --intestinal agglutination; --the presence of real or virtual capsula; --meso-retraction. The frequency of this affection seems to be not negligible in Tunisia. The tuberculosis is the most frequent cause, as an etiology.
